So I was extremely lucky to receive some seeds for testing from @Rhai88 (thanks again) and this will be a diary documenting the findings, traits and environmental bullshit I put them through.
Getting them started in homemade coco plugs with just calmag water, kept in a plastic tub until they germinate as for humidity.
So none of the others have popped up, I’ve taken them out the medium and popped them into some water. A few looked like they’d cracked and started to push out a tap root only to stop. We’ve had very extreme weather here in the UK recently so perhaps that’s a factor.
